IMPROVEMENT IN THE METHODS OF SETTING ARTIFICIAL GEMS.

Specification forming part of Letters Patent N 0. 196,304, datedSeptember 18, 1877; application filed July 30,1877.

To all whom it may concern:

Be it known that We, HENRY P10 and MAURICE NELSON, of Paris, France,have invented a new and useful Improvement in Setting Stones orImitation Substances in Jewelry, of which the following is aspecification:

In the accompanying drawing, Figure 1 represents a front view of ashawl-pin illustrating our improved method of setting stones in articlesof jewelry; Fig. 2, a vertical transverse section of the same on line a;m, Fig. 1; and Fig. 3, a sectional side view of a shawlpin, showing amodified form of construction.

Similar letters of reference indicate corresponding parts.

The object of this invention is to substitute for the soldering andgluing or cementing on of glass, enamel, or other imitation stones ontheir metallic mountings, an improved method of setting the stones inarticles of jewelry for mourning or fancy purposes, by which thebreaking off of the stones from the metallic parts is prevented, and amore durable and neater style of such articles obtained.

Heretofore these articles of jewelry-such as breastpins, brooches,ear-rings, bracelets, lockets, &c.,whether made of glass, jet, or othermaterial, were manufactured in two ways only, namely, either bysoldering the stones on the metal mountings, or by gluing the enamel orglass, by means of a cement likewise, upon the metal base parts ormountlugs.

The invention is intended to overcome the objections to the methodsheretofore employed; and consists of glass and enamel melted on stems,which are riveted, screwed, soldered, or otherwise aifixed to theperforated metallic mountings.

In the drawing, A represents the stones, made of glass, enamel, or othersubstances in imitation of jet or other articles, and B the metal frame,mounting, or device to which the stones for the different articles ofjewelry are applied.

The stones A are melted on stems C, which project from the stones, andserve for the purpose of applying the same in any suitable way to themetallic base-frames, mountings, or attachments, by riveting, screwing,soldering,

or fixing the same, by bending or otherwise, thereto, the stems beinginserted into suitable holes or provided for the purpose.

Either a series or cluster of stones may be attached to a base-framethat is constructed and perforated to correspond to the shape and designof the article, as shown in Fig. 1, or a solid stone, polished torepresent the article, may be attached by one or more stems near theends, and at other places to suitable pin and other attachments, asshown in Fig. 3.

The stones are thereby firmly connected to the metal parts without anydanger of breaking off and marring the appearance and effect of sucharticles.

A substantial and durable class of articles of ornamental jewelry isthus furnished, which gives thereby greater satisfaction, and may beused for a large number of difierent applications.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- 1. As an improvement in the manufacture ofimitation jewelry, stones of glass or enamel melted on. and secured tostems and'attached by the same to metallic frames or mountings,

substantially as and for the purpose set forth.

2. In imitation jewelry, the combination of glass or other imitationstones melted on and secured to stems, with perforated metallic framesor mountings to which the same are screwed, riveted, soldered, orotherwise applied, substantially as specified.

The above specification of our invention signed by us this 9th day ofJuly, 1877.

HENRY PIC. MAURICE NELSON.
